Title: Wind driven turbine for electric power generation - is mounted in purpose built tower to utilise chimney effect
Inventor: ARNTZ OTWIN W
IPC: F03D3/04
Filed: 1976-05-29
Abstract: A tower (1) is built at a suitable location with an inlet at the bottom and an open top. Natural draught chimney effect pulls air through it to increase the effect of the wind. A turbine impeller (2) is mounted in the tower with its axis horizontal in line with one wall of the tower. The entire air flow thus impinges on one half of the wheel while the other half projects out of the tower into a pocket (4) built on the side of the tower. The pocket has an opening into the tower through which air is ejected by the upwards stream. This ejected flow produces an extra drive on the half of the impeller projecting into the pocket.

Title: Nuclear reactor operational control using two regulator mechanisms - esp. control rods for coarse control and core flow for fine control
Inventor: DOI TOSHIAKI
IPC: G21C7/00
Filed: 1977-01-19
Abstract: The operation of a nuclear reactor is controlled by using a first control means (typically control rods) and a second finer control means (typically variation in the flow rate of cooling water through the core) in combination, with the objective of preventing mechanical interaction between the fuel and the cladding material from occurring. The control rods are first withdrawn and, hen the reactor power has reached a level at which fuel-cladding interaction commences, withdrawal ceases; circulation of cooling water through the core is then increased to raise the reactor power to a predetermined level. The reactor power is then held during operation at this predetermined level by using the cooling water flow rate to correct deviation from the desired level. The method applies to a boiling water reactor, in which the flow of cooling water through the core is regulated by injector pumps inside the reactor pressure vessel and circulating water driven by pumps outside the pressure vessel to actuate these ejector pumps.

Title: Signal transmission network with ordering of calls - has central station calling peripheral transmitters in sequence with intervals for urgent signals
Inventor: LANG OTTO ING GRAD
IPC: G08B26/00
